2​020 Supra Engine Torn Down For 1000hp Build

T​hat's a lot of Plastic!

2y ago

The new Toyota Supra is powered by BMW's B58 Straight-6, an engine that's currently more controversial than a decree to ban cat videos from the internet. To figure out if the B58 is a worthy successor to the previous-gen Supra's 2JZ-GTE engine Stephan Papadakis, the owner of Papadakis Racing, took it completely apart. 

N​ow Papadakis Racing knows a thing or two about building high horsepower Toyotas. They're responsible for building Toyota's hugely successful Corolla drift car. That particular drift car uses a version of Toyota's 2AR 4-cylinder that's been tuned to over 1000hp and as you can imagine barely any of it is stock. 

T​he Supra promises to be the future of Toyota's tuning world. There's already a company in Texas offering manual conversions, but how much power can this engine even handle. 

To see if the new Supra's B58 engine is Papadakis Racing's next 1000hp engine they bought a brand new Supra, and immediately disassembled the entire engine. During the teardown, you get a real sense of how modern Toyota, I mean BMW engines are built.

T​here's a ton of clever engineering including the intercooler which is integrated into a plastic intake manifold. The timing chain is located at the rear of the engine which will make servicing and engine out affair. 

Besides the slight oddities, the stand out feature of the B58 is how robust everything seems. Stephan Papadakis notes the stock crankshaft seems worthy of 1000hp right out of the box. The B58 also uses a highly desirable closed deck design which makes the block strong which equals more horsepower potential.

The future seems very bright for 2020 Supra owners looking to pile on the power. The B58 may not carry the same prestige as a 2J but at least BMW didn't skimp during construction. Only time will tell if the B58 can hold a candle to the legendary 2J.

  • So what they’re saying is that the same might be possible with a Z4....? For some reason, the new Supra doesn’t really look like something I’d want to fiddle with. None of the cars in the past 10-15 years have the look. The 90’s were truly the golden age of cars that want to be pushed to the limits and beyond.
